Answer 1

You can make use of Amazon ECS container agent.

The Amazon ECS container agent allows container instances to connect to your cluster. The Amazon ECS container agent is included in the Amazon ECS-optimized AMIs, but you can also install it on any Amazon EC2 instance that supports the Amazon ECS specification. The Amazon ECS container agent is only supported on Amazon EC2 instances.

Installing the Amazon ECS Container Agent

Make sure that the ec2 instance has the IAM role that allow access to ECS before you run the init command
